Notes:
This study investigates a possibility for representing, interpreting and visualising thevibration response of aircraft panels using time domain measurements. The aircraft panels aremodelled as thin orthotropic plates and their vibration response is simulated using FE modelling.The vibration response of a thin aluminium panel is simulated using FE modelling. The first tenresonant frequencies are estimated for the FE model and for the dynamically tested panel. Theywere found to show somewhat low sensitivity to damage. Then the simulated vibration response ofthe panel is transformed and expanded in a new phase space. This presents an alternative way tostudy and analyse the dynamics of a structure. A two dimensional phase space is used in thisinvestigation. Thus instead of studying the single dimension measured vibration characteristics oneis faced with expanded two dimensional variables which can be visualised and this facilitates thecomparison between the damaged and the non-damage states
